[0025] The breathable membrane body 1 includes a non-woven fabric layer 11 and a waterproof surface layer 12 interwoven and fixedly arranged on the bottom side of the non-woven fabric layer 11; a glass fiber layer 13 is interwoven and fixedly arranged on the bottom of the waterproof surface layer 12; a porous nano-membrane 14 with a permeability function is adhesively fixed to the bottom of the glass fiber layer 13; an anti-static structure 15 with a protective function is interwoven and fixedly arranged on the bottom of the porous nano-membrane 14; a bottom membrane 16 is adhesively fixedly arranged on the bottom of the anti-static structure 15.

[0026] The glass fiber layer 13 includes a microporous structure 131 with a diversion function arranged inside it, and a hydrophilic adhesive layer 132 is fixedly arranged on the inner wall of the microporous structure 131; the surface of the non-woven fabric layer 11 is coated with a low-friction coating, and the low-friction coating is made of a mixture of film-forming resin, anti-slip particles and additives. Embodiment 2:

[0027] See also Figure 1~Figure 5 The utility model is a waterproof and breathable membrane with a low-friction pressing structure. Compared with the first embodiment, this embodiment also includes: the waterproof surface layer 12 includes cotton fibers 121, silver fibers 122 and antibacterial fibers 123 interwoven and fixed at the bottom of the non-woven fabric layer 11, and the antibacterial fibers 123 are arranged at an angle of 45 degrees to the cotton fibers 121 and the silver fibers 122.

[0028] The surfaces of the cotton fiber 121, the silver fiber 122 and the antibacterial fiber 123 are all coated with an anti-wear coating 124; the anti-wear coating 124 is made of a mixture of epoxy resin, magnetic color-fixing particles and grease; the cotton fiber 121 is specifically made of ultrafine fiber spinning and twisting, and the ultrafine fiber spinning on the cotton fiber 121 forms a tree-like micro-branched shape.

[0029] The working principle of an improved waterproof and breathable membrane with a low-friction pressed structure is:

[0030] When in use, the non-woven fabric layer 11 provides a protective effect for the surface of the breathable membrane body 1. At the same time, the staggered distribution structure of the non-woven fabric layer 11 and the waterproof surface layer 12 facilitates ventilation with the outside world. The anti-wear coating 124 here can provide anti-friction and water-repellent effects for the cotton fibers 121, the silver fibers 122 and the antibacterial fibers 123. The air can pass through the non-woven fabric layer 11 and the waterproof surface layer 12 in turn into the microporous structure 131 arranged between the fibers of the glass fiber layer 13 for circulation, so as to avoid the existing breathable membrane breathable structure being affected by other multi-layer structures and affecting the breathability effect. At the same time, the hydrophilic adhesive layer 132 and the porous nano-membrane 14 can further adsorb the airflow passing through, and also inhibit bacteria by means of the silver fibers 122 and the antibacterial fibers 123; the good conductivity of the antistatic structure 15 is used to eliminate static electricity, and the silver ions on the surface of the silver fibers 122 can very quickly adsorb the deteriorated proteins thereon to reduce or eliminate the odor, thereby achieving an antibacterial and breathable effect.

[0031] The utility model provides a waterproof breathable membrane with a low-friction pressed structure through improvement. By arranging a composite connection of a non-woven fabric layer 11 and a glass fiber layer 13, due to the characteristics of the glass fiber layer 13 such as high temperature resistance, high tensile strength and good electrical insulation, the surface layer of the breathable membrane body 1 is provided with protection and low friction effect, so that the waterproof breathable composite membrane can be applied to more complex environments; by arranging a waterproof surface layer 12 to absorb moisture from the airflow passing through, it is also antibacterial, and the glass fiber layer 13 and the porous nano-membrane 14 are also used for secondary protection.
